One story my grandfather told about his experience in WWII is when he was part of a wave, he wasn't first wave, but maybe a third or fourth, and they're really trying to get guys and equipment on the beach of Okinawa. The Army is bringing guys in on those boats that open up at the front. One of the guys was sitting on the top edge of the thing, which he wasn't supposed to apparently, and the boat his a huge wave or something and the guy went flying off and out of the boat. The boat driver just kept on going. They never heard from the guy again.
And from that day, my gramps gets to the beach, and the fighting wasn't all that bad. He'd been in the Philippines already and said that was pretty bad stuff and was ready for the worst in Okinawa. And then the Japanese jumped out of their holes and the place was swarming with them. He's still alive and didn't really get into all of it (we knew the previous) until his wife, my grandmother, died. Then he started telling us more for some reason. And it's pretty rough stuff.
Stuff like rape and general sadism amongst some of the soldiers. . . . he doesn't fess up to any of that and I kind of have to believe he didn't participate.
Other stuff is when he was transported by ship around the Pacific. Very few of the Army men on the ships had even seen an ocean, my grandfather certainly had not, and weren't exactly sea-worthy. They were pretty ill. One story he told is where the guys were eating, they'd eat at a table where they could stand while eating, and a guy across from him puked on the food of a guy next to him. All the guys in the area decided they weren't so hungry that day.
Another one was a troop boat he was on where the guys in the room or whatever they call it next to him were screaming and a mess. I asked what was wrong with them (I thought they were being whiners or something) and my gramps said simply, "too much war. They saw too much war."
My gramps was what they called a "runner." He ran messages back and forth which is funny because English is his second language. I guess he carried the messages in his pocket rather than speaking them.
